The tune will calm the popping down a little, but not all the way. I run no baffles. I had a tune done (dont remember the #) but it was either for the Arrow slip ons or an aftermarket setting. A tune is worth it.
I like not having baffles for looks, the end of the pipe is so much more open without them.
